I've had this idea for an embarrassingly long time without drawing it...
hope you enjoyed! The poses weren't as interesting as I intended from the beginning..

These mighty umbrella warriors protect the earth (but mostly Tokyo) from water demons!

From left to right:

Arnold Seller, Rain Posh
Lenore Brown, Rain Mushi
Oben Kuma, Rain Dai
Fujii Cho, Rain Pinku
Aizawa Kojiro, Rain Yamato
and their adorable mentor animal, Ahi-Ahi

As you can see they all have a distinct umbrella and a henshin item pendant thingy they don't really look like they match as a team, but I sacrificed that in the name of unique costumes inspired by various types of rain gear.

To note:
Lenore is based on a pal of mine ( I didn't mean to make her so LITTLE but she could easily grow up as the series goes on.)
Kuma is inspired by Richard Kiel.. though that was kind of an accident.
Arnold was going to be an old bald proper English fellow, but he ended up more like if Xanatos and Daria had a baby.
